<p align="justify">Technology has been developing rapidly in our daily lives and also in Geodesy, these can be seen from the phenomena of commercial use of UAV. Nowadays, studies and mapping projects practice UAV with non-metric camera are frequently can be found. This research aimed to examine orthophoto's geometric accuracy and evaluate airborne videography. Airborne videography is defined as method to acquire aerial video for digital photogrammetry data processing. Engaging UAV DJI Phantom 3 Advanced, Universitas Pertamina in South Jakarta, with area of 7.87 hectare was recorded. The recording was extracted every 4 and 6 seconds to produce 80% and 60% of overlapping consecutive aerial frames. Using Agisoft Photoscan Professional software, all extracted aerial frames are aligned to construct a digital orthophoto. GPS survey was held to measure 12 ground control points and 7 independent check points. Non-metric camera were calibrated using self calibration and laboratory calibration. Five distinct case studies of orthophoto construction are executed and analysed. Ground resolution for orthophoto I, II, and III is 8.46cm / pixel, while orthophoto IV is 8.48cm/pixel and orthophoto V is 3.69 cm/pixel. Geometric accuracy (absolute <br /> <br /> accuracy) of digital orthophoto, representated by RMSEr of orthophoto test I, II, III, IV, and V successively are 6.58 cm; 5.35 cm; 7.86 cm; 7.23 cm; 9.67 cm. Based on ASPRS, all products of orthophoto can be mapped with scale equal to or below 1:500.<p align="justify">
